Yes the embargo is real. The point is, what the above commenter wrote:

> The US starves anyone it does not like from natural resources and subsequently makes them buy US natural resources. It has done this to the EU, now it is trying to do it to China and Cuba

is the complete opposite of an embargo. The US is not making Cuba exclusively purchase oil from the US, it's prohibiting US oil produces from selling to Cuba.

Whatever speculation about what the US will do following some hypothetical regime change is irrelevant.

Are you only here to nitpick semantics?

The statement clearly is not that allowing Cuba to buy resources from the US would be an embargo. The statement is that the US is embargoing (de facto blockading) Cuba today in order to force them to buy from the US tomorrow.
